I am an amateur radio astronomy enthusiast and I've been using an RTL-SDR
(R820T) USB dongle for my projects; up until now I had been using a Windows 8.1
laptop, but that one is on the blink right now so I've switched to a Windows 10
computer. I've tried to plug in my SDR and run the flowgraph (attached), but I
keep getting the output below:

This is being done to prevent the application from crashing
due to gnuradio bug #528.

I've run zadig for the RTL-SDR, and it works just fine with SDR#. Do you have
any advice as to why I might be having this problem with the GNURadio flowgraph?
Thanks very much! Have a great evening and take care,
Ellie
